SPECEFICATON forming part 'of Letters Patent-N0; 630,550, dated .Aug-us Application filed Ang'ust l18, l89i3. Sierisl'No. 688.907.' (No model.) l

To (0M 107mm/ it mrtg/ oww/377i,.- lie it known thatl, GEORGE W. M lima. citi-- zen of the United States, residing; :it Springfield, Illinois, havoinvenied eertziin new and useful improvements in 'lracicbiztndingr Devices, of which the following is :t`,sneeiiioa tion.

The ohjeotof my invention is to" make a .track-sanding device that is. intended ordinarily to be operated hy the vexcess air-pressure used on locomotives and that een oe op- .the slide-irelve mechanism which has long" erated independent of and in con j onction with 'heen used ijn track-sanding devices; and my invention-consists in the features, coinhinations, and details of construction hereinafter described and claimed.

ln the accompanying drawings, liignre l is e, plan View of e send-box, teken in line i oi Fig. 2, empty of sand and with the slide mech-- mism removed; Figr', :t sectional elevation taken in line 2 of Fig. llooking in the direction of the arrow;- end 3, @longitudinal In making my improved track-sanding des vice I employ the usuel sandbox A, providedv with the usual pipes-a for carrying the sand from the box to the track. in the usual con# struction the upper openings-to thesepipes," by which the send in the hex is permitted to dow through the pipes, are closed by slide- Valves which are under the control of the er1- (fineer so that b Y mechanical means he een., b 7

lIn order, however, to impart to the device a.

dual capacity, es it were, so that Iit inlay hev .used either in the old'way or by the .excess air-pressure on the locomotive, I 'leed n pipe -B from the air-reservoir to the send-box, which it enters. The pipe is carried across from oneside of the nox to the other, loeihg` bent orcnrvedl upward, as :itt o, .to'properly They may-bo.

Whenever is desired to epply'sand to thetracln; the engineer admits ei'r under preseenterof the It is fnovidedwi-th two Y ,v bronches D and, D', which lead, respectively,

snre'froi'n thereservoir to the pipe This eir passes along' the pipe until it'reaohes the branch'pipe D 'within the send-box; A portionoi the-entering air. passes` through the.

nozzle end along such. branch, While the remainder foliows-the pipe across the vsandbox and enters the branch D', Where it passes 'through 2, similar nozzleiasit enters such branch. The air thus entering the-branch' pipes in'aljetoreontraeted stream or current is of suiiicient force toA move the sand ahead of it along; the branch pipes, with thes new send constantly entering. and force it intoe/nd ont through the originel sand-.pipes at.

loo'

lf,`however, 'for any reason the' air-pressure pass over Athe' pyrmuidftl elevation (lin the 5 in -the reservoir bo ii'iimicievt, ori the air pumping and compressing mechanism be out of order, or if the air be interrupted, so that air under pressure is not obtainable, the engineer is still able to apply sand to the track by operating the original slide-valve mechA `anism, which is controllable at will by mechanical means. It is thus possible to combine in the saine tracksanding apparatus means for applying the sand either mechanically or through airpressu-re, either separately or together and.simultaneously, so as to insure the presence of means at all times to apply sand to the track, which is not the case where means only are provided for applying the sand mechanically or by air-pressure, as in the one case the sand-pipes may become clogged up or in the other the air give out, become insucient, or`not be applicable. At the same time it is possible to apply my air-pressure mechanism to the original track-sanding devices in use without material expense or trouble either for the additional means or for changes in" the original devices in order to apply them, because, as will be seen, all that isnccessary is to control or provide the device with the holes d and d', intersecting the original sand-pipes, and insert my additional appliance.

\Vhat I regard as new, and desire to secure by Letters Patent, is-

1. Ina track-sanding aliparatus, the conibination of a sand-box provided with twodischarge-duets extending out therefrom and substantially opposite each other, a supplypipe connected with a source ol compressed air and extending diametrically across the box at or near its bottoni portion, a branch pipe extending from each end of the diametrieal supply-pipe inside of the box and connecting such supply-pipe with the dischargeducts, an upward return-bend on the end of each branch pipe where they connect with the discharge-ducts to provide bars to the 4discharge of sand, and a perforation in each branch pipe intermediate the supply-pipe and vtixe return-bend, substantially as described.

L. In a track-sanding apparatus, the combination of a sand-box provided with two discharge-ducts extending out therefrom and substantially opposite each other, a supplypipe connected with a source of compressed air and extending across the box at or near its bottom portion, a branch pipe extending laterally from each end of the snpply-pipeinside ot' the box and connecting such supplypipe with the discharge-ducts, an upward return-bend on the end of each branch pipe where they connect with the discharge-ducts to provide bars to the discharge of sand, a perforation in each branch pipe on the upper side thereof intermediate the supply-pipe and the return-heini, and an injector-nozzle arranged n each branch pipe intermediate the suppl y pipe and the perforation, su bstantally as described.
